zink: resource sync

Mike Blumenkrantz requested to merge zmike/mesa:zink-resource_sync into master

this is a collection of patches which:

  • adds a mechanism for determining how a resource is used on a given batch (read or write)
  • converts existing resource referencing to use this
  • adds further referencing in some places where needed
  • forces transfer map to stall only when necessary based on pending usage

I have a ton of (later) patches which improve upon this architecture, but it does work quite nicely even with this sort of brute force "wait on all fences" approach to fix up a bunch of test cases.
